Well, apparently, that's the only reason they don't, at least according to the lecture. That said, there are lobbyists in every government, so I am sure it wouldn't be so easy to change even if they wanted to.

To me, it is kind of like legalization of guns in America. The place is a goddamn wild west of the 21st century with people carrying guns and shooting each other nearly every day, but the "freedom" to possess guns is not going away any time soon. It is too big a business now.
